' To all whom it may concern Be it known that we,BONNnR W. MASSEY andTHOMAs' J. Goonwm, both citizens of the United States, and residing theformer at East Macon and the latter at South Macon, inzthe county ofBibb and State of Georgia, have invented certain new and usefulImprovements in Valve-Cleaners, of which the following is aspecification.

This invention relates to gage valves, particularly to means forcleaning the same, and is based upon matter divided out of ourapplicationfor Letters Patent of the United States on gage valves andcleaners thereof, filed May '2, 1914, Serial Number 835,890, and. themain object thereof is to provide means for attachment with a valvebarrel whereby the passages through said valve may-be cleane A furtherobject is'to provide such cleaning means which are readily attachable toa portion of the valve barrel from which certain normal parts have beenremoved.

A further object is to provide means whereby the inward passage of thecleaning element may be limited; and further obseparate parts aredesignated by the :same

reference characters and inwhich Figure 1 is a sectional view of ourcleaner in position on a valve barrel, ready for use; and Fig. 2 is anend view thereof, detached from the valve.

The valve is fully described in the application above identified. onlythe barrel and the plug-valve being herein illustrated, said barrelbeing designated 7 and having a hexagonal portion 8 whereby the taperingportion 9 may be screwed into a boiler, and said barrel has a passage 7communicating with a passage 11 through the passage 14 of a plug-valve13 operable by means of a handle 15 and held in position by means of anut 20.

The passage 11' connects with a chamber 11 having a nipple 12 incommunication therewith, and-said chamber 11 is also in communicationwith an enlarged chamber in each of the views,

" cation with the barrel.

31 by means: of a passage 11", the chamber 31 being adapted to reodlvethe packing gland in the normal use of the device as a valve, and thebarrel 7 is screw threaded externally in the position of the chamber 31.Threaded; on this end of the barrel is a cap34: encircling a sleeve 32provided with a flange 33 within said cap, a gasket 35 be ing interposedbetween the flange 33 and the end of the barrel 7, and the sleeve 32 isthus held firmly against and in communi- The sleeve 32 is providedwith athreaded portion 36 and fitted thereon is a cap 37 having a packing 38therein, and through which passes a revoluble stem 39 carrying adrill40, a collar 41 preventing outward movement of the stem 39 by reason ofthe shoulder' ll and which collar is of such diameter as not to be ableto pass through the passage 11 of the barrel, and the stem 39 isprovided with a frusto-pyramidal head 42, which head is adapted to limitthe inward movement of" the drill.

valve barrel is mounted, to an extent whichmight cause damage or injurythereto. lVhen the barrel 7 has been thus cleaned, the parts may beremoved, and the normal valve needle restored in position, and the valveis again ready for normal use.

Having fully described our invention, what we claim as new, and desireto secure by Letters Patent, is

1. As an article of manufacturmfor use with a valve casing having agland engaging screw-thread at one end; of a cleaner, comprising a capinternally threaded to engage the gland thread on said casing, a flangedsleeve held by said cap and rotatable therein, a drill rotatable in saidsleeve,and means for limiting the movement of said drill in either axialdirection.

2. As an article of manufacture, for use with a valve casing having agland engaging screw-thread at one end;.of a" cleaner, comprising a capinternally threaded to engage the gland thread on said casing, a flangedsleeve held by said oaplandrotata- 'ble therein and provided wvithtwoaxial bores of different diameters, a drill having a bearing androtatable in the bore of lesser diameter, means for packing said sleeveand drill'against leakage, said drill having an able collar on saiddrill Within the sleeve bore of greater diameter, said head and col--lar limiting axial drill movement, and said cap, sleeve, and drillforming a unit.

In testimony whereof We have signed our names to this specification inthe presence of two subscribing Witnesses.
